habitat as yet known for it being the "Windsor Falls. (Prof. How, 

 D. C. L. 



Woodsia Hvensis. (R. Brown.) Interesting when placed in 

 a growing collection of Indigenous Ferns, from the contrast which 

 its dull green makes with the brighter green of other species. 

 Habs. — Wycocomah, Cape Breton, (A. W. H. Lindsay, M. D.,) ; 

 rocks on banks of Gold River, near Chester, where it is very abun- 

 dant. Rev. E. H. Ball.) 



Tribe V. Davallie^e. 



Dichsonia punctilobula. (Kenuze.) Interesting as the only 

 indigenous representative of this genus, and as having a pleasant 

 perfume, which is quite perceptible as the plant approaches maturity. 

 Very common. 



SUB-ORDER III. Osmundace^. 



Osmunda regalis. (Lin.) This large and beautiful fern is 

 also common, delighting to grow in running water, its roots being 

 often quite submerged ; but it also abounds in swamps and other 

 moist places. 



Osmunda claytoniana. (Lin.) The specific name interrupta 

 very aptly describes this most beautiful fern which is quite common. 

 Its glory is but short-lived however ; for at the end of June the 

 decayed shrivelled appearance of the fruitful portions of its fronds 

 makes it as disappointing as it is up to that time pleasing. Quite 

 common in moist places. 



Osmunda cinnamomea. (Lin.) A little earlier in springing 

 than claytoniana, and specially to be admired for its reddish brown 

 upright, central, fruitful fronds. But here too, the fruitful fronds 

 soon decay. Very common in swamps and wet places. 



0. 0. var. frondosa. Found by Prof. How, D. C. L., near 

 Windsor, whose specimen is in the Herbarium of Halifax Museum. 



SUB-ORDER IV. Opiiioglossace^. 

 Botrychium simjilex. (Hitchcock.) In the earlier editions of 

 Gray's Manual this is given as a variety of Botr. virginicum, but 

 in later editions as a distinct species, and apparently very correctly
